The inner (3nd of tho beam M connected with the tape 5 for operating the index G and 7 log the pendulum weight I. The 0ppcsitn end of said ljifttlil projects beyond the the oscillation of the beam which is prc'i'orubly mounted in the frame E below the hemp. M and at one side of the stee' mu'd'rod ooi'meotion L which couples the arm 13 with the loo-um l.

l Vith the oonstrurtion just described, the mechanism intermediate the platform and the taro beam forms it manually operable scale which may be employed for Weighing by shifting tho poise M of the beam M. This mechanism is adjusted to be in perfect balance independent of its' attachment to the automatic weighing mechanism. On the other hand, the automatic weigl'iing mechw uism inrluding; the index, a pendulum weight and other conuortions, is also in balance indvpcnd'a-nt oi its connection with the month all oporublo i'veigliing mechanism. This 'lut-i'litntehthe construction and the sealing l of the srulo. l r

O a guide pin projectilr upward from the center of the urui B which extoutls into the portion D ofl tutor-inn and has vonnectocl thereto, a counl titv pour which be provided with deor llllt Weights There is also a dash pot l P for checking shelf and engaging a recess 0" in the ball 0 U 13' a detachable weight which when not in use is supported on a shelf 0 being slot-ted to embrace the pin O. This weight may at any time be removed from the pin and placed on the top of the ball 0} to increase the weighing capacity of the scale.- Thus the pin 0* in connection with the bracket 0 and hollow ball performs the double function of a support for the ole tachable Weight or weights and a guide for checking the oscillations of the counterpoise. The position in which the detachable weight is supported is one very convenient for transferring the weight to and from the ball a of the counterpoise.

W here the beam M is housed in the standard E. the tare beam is preferably arranged as shown in front of said standard and is mounted upon the beam M by connections to the opposite ends thereof. As shown the outer end of the beam M has a laterally extendin arm lV' and the inner end a projecting arm M which latter passes through a slot in the housing E. The tare beam M is attached to these arms M and M and the poise M is slidably secured on this tare beam. Thus the tare beam and poise are in a convenient position for inspection and operation while all of the mechanism is. housed within the standard. 7

The Weighing latform is preferably arranged to theright and forward of the lat-- eral projection D .31" the base and the standard E rising therefrom. This places the poise on the tare beam where it may be most conveniently shifted by the left hand ofth operator. .he same time the fulcrum s the left of its point platform levers. it e 'nust be shifted to Weight and. to the at.

Vfhat I claim as in? invention is:

1. In a scale the cor'ibination with a beam,

i of recessed countergoise attached thereto, a guide for said counter-poise in axial. alinementtherewith and engaging the recess therein, and a shelf on aid guide forming a support for detachable Weights for said counterpoise.

, ted in the oppo 2. In a scale the combination with a fulcrumed beam, of a tare beam mounted thereon and off-set from the plane of the fulcrum, and a steelyard rod for operating said beam engaging a portion. thereof oppositelv Oif-set from the plane of said fulcrum.

3. In a scale the combination with a platform and index and connecting mechanism therebetween, of a beam or lever forming an element of said connecting mechanism, a tare beam off-set in front of the plane of said beam and mounted on'the latter, and a steelyard rod for operating said beam engaginga portion of the latter and oppositely off-set from the tare beam.

In a scale, the combination with a frame, of a beam, a recessed counterpoise attached thereto, a shelf on said frame, a guide carried bysaid shelf engaging the recessed portion of the counterpoise, and a slotted detachable weight adapted to be suption thereof engaging the guide.

5. In a scale, the combination with a base having an extension, platform levers within the base, a platform supported 011 Said levers, an upwardly extending frame above said extension of the base, an indicating sec- .tion on said frame, an index hand and a tare beam both fulcrumed on said upwardly extending frame, a pendulum Weight for said index hand, a steelyard rod connection between. said platform levers and beam, and a connection between the latter and the indeX hand.

6. In a scale, the combination with a base having an extension, platform levers Within the base, a platform supported on said levers, an upwardly extending frame above said extension of the base, an indicating sec tion on said frame, an index hand fulcrumed on said upwardly extending frame, a tare beam fulcrumed on said upwardly extending portion of the frame beneath said index hand, a pendulum weight for said index hand, a steelyard rod connection between -nect1on between the latter and the index hand.

In a scale, the combination. of a base, platform supporting levers therein, a standard on said base, an indicating section carried by said standard, an index, a pendulum Weight, a lever fulcrumed within the standard, a tare beam arranged in front of the an operative connection etween said lever,

the platform levers and said index.

8. In a scale, the combination of a base, a hollow standard rising therefrom, an in- (heating section mounted on the hollow standard, p latform levers arranged in. the base, a platform supported on he levers, a.

lever within said hollow standard, a tare ported onv said shelf with the slotted p0r-.
